He stepped forward then and followed her out. "I am going to motor you home," he said, as he escorted her down the stairs. Dot nearly stopped short in consternation. "Oh, no, really! I'm going home alone. It's no distance, and I know my way perfectly." "I'm coming with you," he said doggedly. But the memory of those eyes that had mocked her across the hall still burned in the girl's heart. She faced him resolutely; "You are not to, Bertie. I don't wish it." "I can't help it," said Bertie. "I am coming." At this point they arrived in the hall, and here she found Lucas Errol waiting to say good-bye to her. She turned to him with desperate appeal. "Mr. Errol, please don't let Bertie see me home. I--I would so much rather go alone." She was almost crying as she said it, and Lucas looked at Bertie with most unaccustomed sharpness. "It's all right," the boy made answer. "We haven't quarrelled yet." The last word sounded ominous, and with her hand in Lucas's quiet grasp, Dot shivered. "But I'm sure we are going to," she said. "And I do so hate quarrelling. Do, please, let me run home alone. I'm not a bit afraid." Lucas began to smile. "I think it's rather hard on Bertie," he said. "However--" "I must go, Lucas," Bertie said quickly. "You don't understand. There is something I want to explain." But Lucas leaned a hand upon his shoulder. "Let it keep, dear fellow. There is always tomorrow!" "No, never, never, never!" whispered Dot to her turbulent heart. Yet when a moment later Bertie came forward, and silently, without looking at her, held open the door, a wild regret surged fiercely through her, and for that second she almost wished that she had let him go with her. And then again there came to her that hateful whisper--that taunting, intolerable sneer; and she fled without a backward glance. Bertie closed the great door very quietly, and turned back into the hall. "Where is Nap?" "Come here, Bertie," Lucas said. He went unwillingly. "Where is Nap?" he said again. Lucas, supporting himself on one side with a crutch, stood by the fire and waited for him. As Bertie drew near he took him gently by the shoulder. "May I know what you were going to say to Miss Waring just now?" he asked. Bertie threw back his head. "I was going to ask her to overlook that cad's vile insinuations--and marry me." "And that was the very thing she didn't want you to do," Lucas said. "I can't help it." There was a stubborn note in Bertie's voice. "She shan't think I'm a blackguard like Nap." "We will leave Nap out of it," Lucas said quietly. "Why?" demanded Bertie hotly. "He was responsible. He insulted a guest under your roof. Are you going to put up with that? Because I'm not!" "My dear fellow, it is I, not you, who must deal with that."
